CSA Exam Dumps - ServiceNow Certified System Administrator

In ServiceNow,record numbers are automatically generated and incrementedby the system. Each record created in a table receives a unique identifier based on a predefinednumber format.

Each table that extends the "task" or other core tables has a default numbering format.

Numbering is automatic, meaning users donothave to manually increment numbers.

The numbering format follows aprefix + incremental number(e.g., INC0001001 for incidents, CHG0002001 for changes).

The system ensuresunique sequential numberingwithin each table.

How Record Numbering Works:Configuring Auto-Numbering:Admins can customize numbering formats by modifying the"Number Maintenance"module:

Navigate toSystem Definition → Number Maintenance.

Select a table and configure theprefix, length, and starting number.

Changes apply automatically to new records created in that table.

Record numbersdo not require manual updates; the system handles it automatically.

Users can changeformat settings, butcannot manually increment individual record numbers.

ServiceNow prevents duplicate numbers to maintain data integrity.

Why "False" is the Correct Answer:

Manual incrementing isnotrequired or possible for individual records.

The platform automatically assigns the next sequential number to each record.

Why "True" is Incorrect:

ServiceNow Documentation:Number Maintenance

CSA Exam Guide:Coversautomatic record numbering and Number Maintenance settings.

Reference from CSA Documentation:Thus, the correct answer is:

B. False

AData Policyin ServiceNow is used to enforcemandatory and read-only field conditionsfor data that isentered manually through forms or imported into the system.

Data Policies apply to data coming from external sources, such asimports, web services (API), and integrations.

If a field is set asmandatoryin a Data Policy, recordscannot be imported unless that field contains a value.

This ensuresdata integrityby preventing incomplete or invalid data from entering the system.

If an administrator configures a Data Policy to make the "Caller" fieldmandatoryon theIncidenttable, any imported incidentswithout a Caller value will be rejected.

How Data Policies Enforce Mandatory Data on Import:Example Scenario:

Why "True" is the Correct Answer:Data Policies enforce mandatory fields for both UI entry and imports.

Why "False" is Incorrect:If Data Policies didnotenforce mandatory fields on imports, incomplete records could enter the system, leading to data integrity issues.

ServiceNow Documentation:Data Policies

CSA Exam Guide:CoversData Policy enforcement for UI forms and imports.

Reference from CSA Documentation:Thus, the correct answer is:

A. True

Update Setsin ServiceNow are used tocapture customizations and configurationsmade in an instance, allowing these changes to be moved between instances (e.g., from development to test or production). ServiceNow provides best practices to ensure smooth migration and avoid issues with missing or conflicting updates.

What is an Update Set?

AnUpdate Setis a collection of customizations (e.g., changes to forms, scripts, workflows, business rules) that can be moved from one instance to another.

Ittracks changesin a controlled way, preventing accidental loss of configurations.

Why Avoid Using the Default Update Set?

TheDefault Update Setis automatically used when no other update set is selected.

It captures changesbut should never be used for instance-to-instance migrationsbecause:

Itcannot be exported.

It contains system changes that arenot logically grouped.

It can causeinconsistencies and missing dependencieswhen moving updates.

Instead, administrators shouldcreate a named Update Setfor specific development work.

Understanding Update Sets in ServiceNow:

Why Answer "A" is Correct:✔️"Avoid using the Default Update Set as an Update Set for moving customizations from instance to instance."

This follows ServiceNow’sbest practicesfor managing Update Sets.

Using theDefault Update Setcan lead tomissing updates, conflicts, and untracked changes, making migrations unreliable.

Why the Other Answers Are Incorrect:B. "Before moving customizations from instance to instance with Update Sets, ensure that both instances are different versions."

Incorrectbecause ServiceNowrecommends that instances be on the same versionbefore applying Update Sets.

If instances are ondifferent versions, the Update Set may includeincompatible changes, causing failures.

C. "Use the Baseline Update Set to store the contents of items after they are changed the first time."

Incorrectbecause there is no such thing as a "Baseline Update Set" in ServiceNow.

ServiceNowdoes not automatically create a backup of original configurations—administrators should manually create an Update Set before making changes.

D. "Once an Update Set is closed as 'Complete,' change it back to 'In Progress' until it is applied to another instance."

Incorrectbecausea completed Update Set should not be reopened.

Once markedComplete, an Update Set isready for export and migration. Reopening it can causedata integrity issuesand confusion in version control.

ASchema Mapin ServiceNow is a graphical representation of tables and their relationships within the database. It helpsadministrators and developersunderstand how data is structured and interconnected.

Visual Representation:Showsparent-child relationships,reference fields, andextensionsbetween tables.

Database Schema Navigation:Enablesquick accessto table structures and fields.

Impact Analysis:Helps inassessing changesbefore modifying fields, tables, or relationships.

Enhances Development Efficiency:Aids in customizing the system by understanding data dependencies.

Navigate to:System Definition → Schema Map

Select a Table:Enter a table name (e.g.,incident,task)

View Relationships:The map will display related tables (e.g., extended, referenced, and referencing tables).

Key Features of a Schema Map:How to Access Schema Maps:

A. A schema map enables administrators to define records from specific tables as trouble sources for Configuration Items– Incorrect.

Schema mapsdo not define trouble sources; they are used to visualizetable relationships.

B. A schema map graphically organizes the visual task boards for the CMDB– Incorrect.

Visual Task Boardsare separate from schema maps and are used for task management, not database visualization.

C. A schema map graphically displays the Configuration Items that support a business service– Incorrect.

This describes aDependency View, which is part of theCMDB, not the Schema Map feature.

ServiceNow follows asingle-instance, single-tenant architecture,nota multiple-tenant architecture. This means:

Single-Instance:

Each ServiceNow instance is aunique, independent environmentfor a customer.

All customers have their own dedicated instance with their owncustom configurations, data, workflows, and applications.

ServiceNow instances are hosted in amulti-instance cloud modelrather than a multi-tenant model.

Single-Tenant Model (Multi-Instance Architecture):

Unlikemulti-tenant architectures(where multiple customers share the same application and database), ServiceNow provideseach customer with a separate, isolated instance.

Thisensures data security, performance isolation, and customization flexibility.

Each instance has its owndata storage, configuration, and upgrade schedule, reducing risks associated with shared environments.

Why ServiceNow Uses Multi-Instance Instead of Multi-Tenant:

Security & Data Isolation:Since each customer has an independent instance, there isno risk of data leakagebetween tenants.

Customization & Flexibility:Customers cancustomizetheir instance freely without affecting others.

Performance & Scalability:Each instance can bescaled independently, ensuring optimal performance.

ServiceNow does NOT use a multiple-tenant architecture.

ServiceNow follows a single-instance, single-tenant (multi-instance) model.

Each customer has a dedicated instance with isolated resources and configurations.

A multi-tenant architecturemeans multiple customerssharethe same application/database with logical separation, which is NOT the case in ServiceNow.

ServiceNow instead provides separate instancesfor each customer, meaning it isnota true multi-tenant system.

Why Option B (False) Is Correct?Why Option A (True) Is Incorrect?References from Certified System Administrator (CSA) Documentation:

InServiceNow,Access Control rules (ACLs)are used torestrict or grant accessto data. Each Access Control rule consists of:

Table-level (Row-Level) ACLs– Control access to the entire record (row).

Field-level ACLs– Control access to specific fields within a record.

Access Control rules are evaluated in a specific orderto determine whether a user has the necessary permissions to perform an action (Read, Write, Create, Delete, etc.).

If both a row-level and a field-level ACL exist for the same table, BOTH must evaluate to "true"before access is granted.

The system checks conditions, scripts, and roles defined in the ACLsto decide whether the user meets the access requirements.

Access Control Rule Evaluation Process:Why is Option C Correct?If both a row-level rule and a field-level rule exist, both must evaluate to "true" for a user to perform an action.

Row-Level ACLscheck if a user can access the record itself.

Field-Level ACLscheck if a user can access specific fields within that record.

If a user failseitherACL check, access is denied.

Why Are the Other Options Incorrect?A. "Rules are evaluated using roles. The role with the most permissions evaluates the rules first."

Access Control rulesare not evaluated based on roles with the most permissions.

Roles are just one factorin ACL evaluation, along with conditions and scripts.

B. "If more than one rule applies to a row, the older rule is evaluated first."

ServiceNow does not prioritize ACL rules based on their creation date.

Instead, ACLs follow a structured evaluation order (general-to-specific).

D. "Rules are evaluated from the general to the specific, so a table rule must be active to continue."

This is partially true but misleading.

ServiceNow evaluates ACLs fromspecific to general(Field → Table).

However,a table-level rule does NOT need to be activefor a field-level ACL to be evaluated.

Reference from Certified System Administrator (CSA) Documentation:📌ServiceNow Docs – Access Control Rules (ACLs) Evaluation

🔗ServiceNow ACL Evaluation Documentation

"If a field-level rule and a row-level rule exist,both must evaluate to truefor the operation to be allowed."

Conclusion:The correct answer isC. If a row-level rule and a field-level rule exist, both rules must be true before an operation is allowed.

🔹Understanding ACL rule evaluation is critical for managing security in ServiceNow, ensuring that users have the appropriate access while maintaining data integrity.

AUI Actionin ServiceNow can be configured toprompt or notify users when an action is completed, such as submitting an Incident. UI Actions are used to createbuttons, links, or context menu itemsthat trigger specific actions.

AUI Action(e.g., a "Submit" button on the Incident form) can be configured with asuccess messageusing thegs.addInfoMessage()function.

This message is displayed after the form submission to inform the user that theirIncident has been successfully submitted.

How UI Actions Can Prompt a Success Message:Example of a UI Action Script:javascript

CopyEdit

gs.addInfoMessage("The incident has been successfully submitted.");

This will display aconfirmation messageat the top of the page when an Incident is submitted.

Why "True" is the Correct Answer:UI Actions can display confirmation messages usinggs.addInfoMessage()or similar methods.

Why "False" is Incorrect:UI Actionscanbe used to provide user feedback, including success messages for actions like submitting an incident.

InServiceNow, aDictionary Overrideallows an administrator tocustomize the properties of a fieldin achild tablewithout modifying the field in the parent table.

This is particularly useful intable inheritance scenarios, where a child tableinherits fields from a parent tablebut needs different behavior for certain fields.

Modify field properties(e.g.,mandatory,read-only,default value) inextended tables.

Preserve inheritancewhile allowing exceptions for specific child tables.

Avoid modifying the original dictionary definitionof a field at the parent table level.

Key Functions of Dictionary Overrides:Example of Dictionary Override in Action:Consider theTask Table (task), which is aparent tablefor many modules likeIncident, Change, and Problem.

TheTask Tablehas apriorityfield.

If theIncident Table (incident)needs to override thepriorityfield tomake it mandatory, an administrator can create aDictionary Overridefor thepriorityfield in theincidenttable.

Thepriorityfield in other child tables (e.g.,change_request,problem) remainsunaffected.

(A) A Dictionary Override is an incoming customer update in an Update Set which applies to the same objects as a newer local customer update – Incorrect

This definition describesUpdate Set Collisions, not Dictionary Overrides.

Update Set Collisions occur whenan update set applies changes to an object that has been modified locally.

(B) A Dictionary Override is the addition, modification, or removal of anything that could have an effect on IT services – Incorrect

This describesChange Management in ITSM, which tracks changes to IT services.

Dictionary Overrides specificallymodify field propertiesin extended tables.

(C) A Dictionary Override is a task within a workflow that requests an action before the workflow can continue – Incorrect

This describesApproval Actions in Workflows, not Dictionary Overrides.

Workflow approvalspauseexecution until an action is completed, but Dictionary Overrides donotfunction this way.

(D) A Dictionary Override sets field properties in extended tables – Correct

This is the correct definition.

Dictionary Overrides allow admins tocustomize field behavior in child tableswhile maintaining inheritance from parent tables.

Explanation of Each Option:

Use Dictionary Overrides sparinglyto avoid unnecessary complexity.

Always test changes in a sub-production environmentbefore applying them in production.

Document overrides properlyto help future administrators understand why an override was applied.

Use the "Dictionary Entry" (sys_dictionary) tableto view and manage dictionary overrides.
